Serial No. 725,302.

To all whom t may concern Be it known that we, Hman C. Giens and lllivrrrnis G-ANGLER, citizens ot the United States, residing at Chicago, in the county olf Cook and CState of lllinois, have invented new and useful Improvements in (lageocks, of which the following is a speciiication.

This invention relates to a gage cock ttor steam boilers and the principal object oit the invention is to provide a cock ot this character wherein the Valve seat or pin may he `around with a tull head of steam on the boiler.

The invention consists essentially in a casing; having' two spindles operatively arranged therein with seat engaging pins on their ends and the device is so adapted that when one spindle is disabled. the other spindle may he brought into play to determine the amount of water or steam in the looiler.

Further objects ot the invention will appear as the l'ollowinnf specific description is read in connection with the accompanyingT drawing` which forms a part of this application, and in which :M i

Figure 1 is a longitudinal sectional View. Fig. 2 is a transverse vertical sectional View on the line 2-2 of liigr. 1.

Referringr more particularly to the drawing 1 represents the casing' which has a longitudinal extension 2 threaded at its end to enter the boiler, and provided with a central longitudinal here 8 communicating with an enlarged chamber t in the center oli the casing. it the juncture of the here 3 with the chamber 41 a valve seat 5 is :formed against which is adapted to rest the pin and body ot a valve spindle 7. This valve spindle threaded as shown at S so as to he adjustable in the nipple 9 which is alined with the extension 2 upon the opposite side ont the chamber l. The spindle is packed in the usual manner by a packing 10.) a packing sleeve 11 and a packing` nut 12 which forces the packing' sleeve against the packing' and the latter against a shoulder 1B formed in the nipple. Extending); at right angles to the extension and the nipple 9 and slightly olifsct therefrom is a nipple 1&1 and a discharge nozzle 15 th e latter provided. wit-h a central bore 16 which alines with the bore 17 in the nipple 111-. The bore 1G communi- Cates with the chamber 4 and the valve seat 1S is termed at the juncture of the bore 16 in the chamber Il to receive the pin end 19 ot' the spindle 20. Both spindles are provided with handles as shown at 21 and 22 for the manipulation of the same.

ln operation the spindle 7 has its pin end removed trom the seat 5 and the spindle 2O is used to close the discharge through the here 1G. tilh ould the spindle 20 become worn on the pin or spring; a leak the spindle 7 can he operated to close the passage through the here 5l and the spindle 2O can be removed and ,around and then replaced. Should the spindle 20 become so disabled that it could not he used the spindle 7 could be utilized to test the holler.

lllhatis claimed is :H

A gane cock comprising; a cruciform casing` having a longitudinal loore and an offset transverse bore communicating' therewith, and valve spindles mounted in the casing` and crossing each other, one of the bores adapted to connect with a boiler and the other boro openinginto the atmosphere, both valves adapted to independently close communication between the boiler and the atmosphere.

ln testimony whereof we affix our signa tures in presence ot two witnesses.
